  1. IQR refers to interquartile range, ICC refers to Intraclass Correlation Coefficient
  2. ICC: 0.00 to 0.20 poor, 0.21–0.40 fair, r = 0.41–0.60 good, r = 0.61 to 0.80 very good, r = 0.81 to 1.0 excellent [32]. *Refers to significant correlation at p < 0.05, SDC: smallest detectable change, MD: Mean Difference
